摘要： A buried heterostructure type distributed feedback semiconductor laser comprises a semiconductor substrate transparent to an oscillation light beam, a laser stripe including a diffraction grating, an active layer, and a guiding layer formed on the semiconductor substrate, and semiconductor peripheral region formed so as to cover the laser stripe on the semiconductor substrate. The semiconductor peripheral region is transparent to an oscillation light beam. Rectangular grooves are formed near both sides of emission facet of the laser stripe more deeply than the laser stripe. Since a radiation mode from the laser stripe is reflected and scattered by the grooves, it cannot hardly reach the emission facet. Therefore, the radiation mode does not interfere with an output beam from the laser.

摘要： Disclosed is a grating-coupled surface emitting laser capable of obtaining a beam with high directivity, structured by forming a light output window in a limited regions with high intensity radiations along the propagation direction. Its intensity distribution of radiation mode along the axis can be controlled by injecting a current independently into the multiply-divided electrodes or by pumping optically these electrodes independently. The control is, in principle, achieved by an equivalent change of the phase-shift of the gratings.

摘要： A medium having the function of light emission or optical amplification induced by optical pumping is surrounded by an annular laser (ring laser) having a diffraction grating (holographic structure) of the second order or more. The output of the ring laser emits through this diffraction grating (holographic structure) and is extracted as radiation mode. This is used as pumping light to be input to the medium that is disposed in the vicinity of the center of the assembly. To stabilize the threshold of the longitudinal mode, which has a greater amount of radiation mode, a gain medium and a reflective structure could be further provided around the periphery of this ring laser. This element also plays a role of optical pumping from the sides of a VCSEL.

摘要： Disclosed are a semiconductor light emitting element whose temperature characteristics are compensated for so as to provide a stable temperature characteristics in a temperature range from -40.degree. C. to +85.degree. C., and an optical fiber transmission system using the same semiconductor light emitting element. In the semiconductor light emitting element, an active layer (2) is buried on an n-type InP semiconductor substrate (1) formed with an n-side electrode (21). The upper layers (4, 5) are covered with an insulating film (22). A p-side electrode (20) is formed on the uppermost layer of the semiconductor substrate so as to cover the insulating film (22). A relatively large metallic resistance element (30) whose resistance increases with increasing temperature is wired on the insulating film (22) as a shunt path, so as to compensate for the temperature characteristics of the semiconductor light emitting element. Therefore, since leakage current is large at a low temperature, the threshold current is high, so that the slope efficiency is small. On the other hand, since leakage current is reduced at a high temperature, a rise in the threshold current and a drop of the slope efficiency can be both compensated for.

摘要： A linear active layer, a current block layer and a clad layer are formed on the first major surface of a wafer, while a first electrode is formed on the second major surface of the wafer. A linear first opening is formed in the first electrode. The wafer exposed to the first opening is etched to form a first guide groove linearly extending in a direction perpendicular to the active layer. A second electrode is formed on the clad layer and etched to form a linear second opening therein. The clad layer, current block layer and wafer, located directly under the second opening, are etched to form a second guide groove thereon so as to extend in a direction parallel to the active layer. The wafer is cleaved along the first guide groove to form bars each having semiconductor lasers. The bars are arranged in parallel to one another and separated from one another by the second guide groove. The wafer is cleaved or cut along the second guide groove to obtain semiconductor chips.
